Abstract

The present invention provides a drum type washer (10), by which a drum opening can be correctly aligned with a tub opening without a physical contact with a drum (30) or motor (40) using a position detection sensor. A tub (20) has a tub opening on an upper side and brackets on front and rear ends to support bearings, respectively. A drum (30) is provided within the tub (20) and has a washing chamber (31) inside. A door is provided over the tub to open/close the tub opening. A motor rotating the drum, includes a rotor (100) provided to an outside of the motor, the rotor including a rotor frame (170) made of a steel plate in one body, magnets (110) attached to an inner circumference of the rotor frame (170), and a position indicator magnet coupled to one side of the rotor frame. A stator (200) provided within the rotor includes a hole sensing unit (210) having a speed detection hole sensor (213) detecting a plurality of the magnets and a position detection hole sensor (214) detecting the position decision magnet (300). A washing shaft (50) is coupled to a front center of the drum (30) and the motor, and an assist shaft (51) is coupled to a rear center of the drum.
